To all whom it imty concern.-

Be it known that I, THOMAS ALBERT BLAKELY, of the village of Flesherton, in the county of Grey and Province of Ontario, Canada, have invented certain new and useful Improvements in Antifriction-Bearings; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an antifrictionbearing for a shaft or axle in which the bearing-rollers are preferably spaced and maintained in correct alinement by antifriction spacing means consisting of spacing-balls or spacin -rollers positioned to engage the trunnions OI the bearing-rollers and maintained in contact therewith by bearing-rings contained within the journal-box.

For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which I Figure 1 is a perspective view of a section of a line-shaft, journal-box, and the antifriction-bearing. Fig. 2 is a longitudinal sec-' tional view of the construction shown in Fig. 1. Fig. 3 is a transverse sectional view of the construction shown in Fig. 1. Fig. 4 is a perspective view of the construction shown in Fig. 1 with part of the bearing-rings removed to illustrate the arrangement of the bearing-rollers and spacing means. Fig. 5 is a similar view to Fig. 3, showing antifriction-balls used as the spacing means.

Like letters of reference refer to like parts throughout the specification and drawings.

The journal-box is composed of two sections a and 0, having flangesb and 6, respectively, with alining bolt-holes 0 for the clamping-bolts (Z, by which the sections a and a are securely fastened together to form the journal-box. Contained within the box are two bearing-rings e and a, each composed of two separable sections having flanges f and alining bolt-apertures for the fastening-bolts g, which securely lock the bearing-ring sections together. The flanges f are contained in flange-seats it within the journal-box and journal-box flanges, so that when the journal-box sections are fastened together they will engage the bearing-ring flanges and hold the bearing-rings immovable in their fixed position. Each of the bearing-rings eand a consists of a rim i and a side plate j, having a bore alining with the bore of the journal-box for the line-shaft it. Encircling the line-shaft 7 between the bearing-rings c and a are antifriction-rollers Z, the ends of which are slightly removed from the inner edges of the bearingring rims 2', and projecting within the rims z' are the bearing-roller trunnions m, the ends of which are slightly removed from the side plates 1', so that each bearing-roller may creep for a limited distance longitudinally in each direction and be prevented from binding against the bearing-rings during its individual revolution around its own axis or the collective revolution of all the bearing rollers around the axis of the shaft. To maintain the correct alinement and spacing of the bearing-rollers, antifriction spacing means 727/ are interposed between the trunnions m. As shown in Figs 1, 2, and 3, these antifriction spacing means consist of spacing-rollers of a shorter length than the length of the trunnions and of such a diameter that they will contact the trunnions and hold the bearingrollers correctly spaced under all conditions of load and action, and, as shown in Fig. 5, the antifriction spacing means consists of spacingballs on", engaging the trunnions similarly to the spacing means shown in the previouslymentioned figures.

The rims of the bearing-rings prevent the radial displacement outward of the bearingrollers and antifriction spacing means by engaging the bearing roller trunnions and spacers, while the radial displacement inward of the bearing-rollers and spacing means is prevented by their contact with the line-shaft, and the longitudinal displacement of the bearing-rollers is limited by the contact of the bearing-roller ends against the inner edges of the bearing-ring rims, while the longitudinal displacement of the spacing means is limited by the bearing-ring side plates and the bearingroller ends. The revolution of the line-shaft causes the independent revolution of each bearing-roller around its own axis and the collective revolution of the bearing-rollers around the axis of the lineshaft, so that the wear will be evenly distributed to each bearingroller and to each part thereof, and to reduce the friction the bearing-rings are spaced so that the bearing-rollers will be free to move longitudinally in each direction between them, so that should either end of any or all of the bearing-rollers contact the edge of the adjacent bearing-ring rim such bearing-roller or bearing-rollers will move in the opposite dithe revolution of the bearing-rings may be rection to clear it or themselves of contact therewith.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An antifriction-bearing comprising a journal -b0X having a longitudinal bore therethrough and composed of two separable sections having projecting flanges with alining apertures and fastening bolts to extend through said apertures and fasten the separable sections together, said journal-box sections and flanges having Within their inner faces recesses, sectional bearing-rings composed of annular rims and side plates with longitudinal bores alining with the bore of the journal-box and flanges with alining bolt-apertures and fastening-bolts passing through said apertures to fasten the bearing-ring sections together, the bearing-ring flanges being located within the journal-box recesses so that prevented, bearing-rollers arranged in an annular set between the bearing-rings and of such a length as to have a limited longitudinal movement in each direction between them, there being trunnions for the ends of the bearing-rollers contained within the bearing-ring rims, and antifriction-spacers contained within the bearing-ring rims interposed between the bearing-roller trunnions, the edges of the bearing-ring rims being opposed to the bearingroller ends to limit the longitudinal movement of the bearing-rollers in each direction, the longitudinal movement of the antifrictionspacers being prevented by the bearing-ring side plates and bearing-roller ends.
